I just picture a scenario where Newt and Credence are either at the MACUSA Pool or gym and they are both feeling a little self conscious when suddenly they see Percival bursting out of the water of the pool in nothing but tight bathing trucks or working out in a tank top that shows off rippling muscle. Newt and Credence all but gawk at him, and then feel irrational jealously when they notice that others are appreciating Percival as well.

Percival is effortlessly graceful as he moves, adding to the attractiveness. Newt and Credence both think that Percival doesn't notice them, but he does and he decides that he'll take any chance he can to fluster the two gorgeous young men he's secretly been pining after ever since he returned to his life after Grindelwald.
